how to learn coding basics. A very good way to learn App Inventor is to read the free Inventor's Manual here in the AI2 free online eBook http://www.appinventor.org/book2 the links are at the bottom of the Web page. The book 'teaches' users how to program with AI2 blocks. There is a free programming course here http://www.appinventor (The default color is white text on black but the color properties, as well as the text size, may be changed in the App Inventor Designer.) When this screen is displayed the user may touch an item in the list to select it. Use ListPicker whenever you have a set of items from which the user is expected to make a selection. Example applications could include selecting a product from a list of inventory items, select a food item from a menu, select a name from a display of names and.

If so, it should be easy to meet your requirement, the problem is that you cannot multi-select from the ListPicker, you can only select one row at a time. However, if the total number of times you make a selection is always the same (in your example, three rows are selected) then you can display the ListPicker programmatically for the remaining two picks (via a Procedure, using call ListPicker Open)

In December, I was trying to get a listpicker to change lists and stay open. Eventually, I found out that couldn't happen and decided to switch between 2 listpickers, going back and forth as the lists change. I then ran into another problem, which was that the first listpicker was not switching lists, and it was only showing the preset list. I figured out that it was because of the set.listpicker block in the before picking event handler The ListPicker component shows the user some choices and lets her choose. It has an associated button. When the button is clicked, the chooser appears over the entire screen. The user chooses, and the UI reverts back to its previous state. The BeforePicking event is triggered when the user clicks the ListPicker's associated button. Generally you'll set the ListPicker's Elements property here. Elements is a list and its items are what appears in the chooser. In this sample, ListPicker.

BeforePicking() Event to raise when the ListPicker is clicked or the picker is shown using the Open method. This event occurs before the picker is displayed, and can be used to prepare the picker before it is shown (The default color is white text on black but the color properties, as well as the text size, may be changed in the App Inventor Designer.) When this screen is displayed the user may touch an item in the list to select it. Use ListPicker whenever you have a set of items from which the user is expected to make a selection lists and a multiple-choice quiz app. Many apps process lists of data.
